A barge refers to a small ship that transports cargo in ports, inland seas, lakes, rivers, and canals.

Such barges are used as ships next to the main ship to carry cargo between two points or to load and unload cargo in cases where large ships cannot berth in the port.

Most barges are non-powered ships that are configured to navigate by tugboats or pushed by a smuggler. However, some self-propelled barges are also equipped with thrusters.

The size is indicated by the load of cargo and ranges from hundreds to tens of thousands of tons.

Among them, a catamaran type barge is a representative, which is a catamaran-shaped barge with a pair of hulls attached to the lower sides of both sides of the deck.

It is preferable to use a center beam that is relatively thicker and has a larger width than the main beam 130.

However, a bow frame 160 is separately provided on the bow side of the hull 100.

The bow frame 160 is formed in a square frame shape similar to the main frame 110, but has a smaller area than the main frame 110.

In addition, one or more bow frames 160 are arranged in parallel, and the area gradually decreases toward the front. To this end, as shown, the vertical length of the bow frame 160 is the same as that of the main frame 110, but the horizontal length is arranged in an order of gradually decreasing.

In addition, the upper center beam 141 and the lower center beam 142 are formed to be longer than the main beam 130 and protrude toward the bow, and the bow vertical beam 161 is vertically coupled to the bow end. The stern vertical beam 171 is coupled to the side end.

It shows a schematic diagram and a side schematic diagram. Here, Fig. 8(a) shows the bottom plate of the hull, and Fig. 8(b) shows the side plate of the hull.

In the present invention, a closed lower space may be formed under the hull 100 to provide a structure for receiving ballast water.

To this end, an intermediate plate 190 may be further inserted and installed horizontally in the middle of the interior of the hull 100.

A flat plate-shaped intermediate plate 190 is further provided between the bottom plate 152 and the side center beam 143. The upper side of the intermediate plate 190 may be divided into an upper space and a lower side of the intermediate plate 190. This lower space is sealed and formed by the partition wall 120 and the partition wall 120 and the intermediate plate 190 and the bottom plate 152.

An inlet check valve 193 may be installed on the bottom plate of the hull 100 to allow water (ballast water) to flow into the lower space. The inlet check valve 193 is a check valve that is opened to allow water to flow into the lower space by water pressure from the outside, but blocks the water from being discharged.

In this case, a plurality of inlet check valves 193 are provided, and it is preferable to be installed one for each lower space partitioned by the partition wall 120.

In addition, a discharge check valve 194 may be further provided for each lower space.

The discharge check valve 194 is a valve that allows water in the lower space to be discharged to the outside as opposed to the inlet check valve 193, and is opened so that the water in the lower space is discharged to the outside when the pressure inside the lower space increases. , It is a check valve that blocks the inflow.

In addition, a plurality of air check valves 191 are further provided on the intermediate plate 190.

The air check valve 191 is for forcibly injecting compressed air into the lower space, and is a check valve that is opened only when injected into the lower space from the outside.

Each air check valve 191 is connected by an air pipe 192 line, and the air pipe 192 line extends to the outside, that is, the deck 200 to inject compressed air from the outside.

That is, when the inlet check valve 193 is opened by the water pressure and a certain amount of water flows into the lower space, it functions as a ballast water. At this time, the discharge check valve 194 is not opened because the external water pressure is large. .

Conversely, when air is injected through the air check valve 191 to discharge ballast water, water in the lower space may be discharged through the discharge check valve 194.

For reference, drain holes 195 are formed in the main frame 110 and the partition wall 120, respectively, so that water from one side may flow to the other side. That is, the water flowing into the lower space is distributed evenly.

In this case, the drain hole 195 may be disposed differently in height.
